i'm sure you'd be lonely at some points. that doesn't mean that living alone is a bad thing. only you would know for sure if you'd be comfortable with living alone, even with the loneliness that will come sometimes. hell, people get lonely sometimes living WITH someone. it's a part of being human.
only you will be able to determine if you can afford it. i'd say if you're not financially responsible, then no, don't get a place of your own. if you are, then you can make it happen, one way or another.
i think that people can learn a whole lot about themselves while living alone. even if, when the time comes, you are no longer living by yourself and you realize you didn't enjoy it, i'd still say that it can't be a bad thing. it just might strengthen parts of yourself to make yourself better.
good luck, whichever way you decide to go. there is no right or wrong answer here.
